"No man for debt shall go to jail
While he can Garryowen hail"

are the words sung in the Errol Flynn film by "Queen's Own", a Hollywood caricature of an English "toff" ( complete with monocle), who nevertheless has one of the best lines in the whole screenplay. On Custer trying to get him to take a dispatch back to Fort Lincoln, since it's "an American fight" coming up, the character replies,

"The only real Americans are out there wearing war paint and feathers".

Incidentally, the set of words beginning "we may rove through the World..." mentioned above are by Thomas Moore.
